The device addresses engineers’ most pressing traction motor challenges- including vibration at startup and running mode, high rotational speed, mechanical space constraints, high operating temperatures, and ISO 26262 safety requirements. The sensor is capable of high speed switching up to 40kHz for 30k RPM operation, it comes with advanced algorithms to suppress undesired output pulses at startup and running mode. The patented integrated magnet package reduces design complexity and enables overall smaller motors, for operation at temperatures up to 160°C. The ATS17501 incorporates real-time diagnostics to achieve an ASIL-B(D) rating as a safety element out of context.
